Answer:5 per person
Step-by-step explanation:
10/2=5
For implicit, you take the derivative of entire equation. When it is a function of 'y', you must multiply derivative by ' dy/dx'.
For this example, f(x) = x^4, g(y) = cot(y)
After differentiating, solve for 'dy/dx':
You will need to give at least 2 values to plug in to solve the equation.
However, to solve for a single variable, you need to isolate it.
See picture taken as in how to solve for one variable.
Answer:
11.2
Step-by-step explanation:
x is the length of a radius of the circle, all radii have the same length.
the chord of length 20 is perpendicular to the segment of length 5, so the segment bisects the chord , so half of the chord is length 10.
The segment of length 10 is one leg of a right triangle while the segment of length 5 is the other leg. The hypotenuse is also a radius of the circle.
The length of the hypotenuse can be found by they Pythagorean Theorem, a^2 + b^2 = c^2, so
5^2 + 10^2 = c^2 or
25 + 100 = c^2 or
c^2 = 125 or
c = = ≈ 11.2
so if one radius is approximately 11.2, then all radii (including the one of length x) are 11.2
9 + - 24
a positive and negative make a negative, so the question is actually
9 - 24 which is -15
